I had the recall from Ram for the ecodiesel recall and now the truck is complete unsafe. I can't even accelerate into traffic without getting nervous. The truck lags and the throttle response is terrible now. Instead of buying them back like Volkswagen did, Chrysler put us in death traps.

The contact owns a 2015 Ram 1500. While driving 70 mph with the cruise control engaged in eighth gear, the vehicle downshifted into sixth gear. In addition, the check engine warning indicator illuminated and the fuel mileage decreased. The vehicle was taken to carlock Chrysler Dodge Jeep Ram Fiat of tupelo (966 cross creek dr, Saltillo, ms 38866, (662) 842-2277) where it was diagnosed that the egr cooler burst and was leaking. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and referred the contact to the local dealer. The failure mileage was 72,435.

Did the aem recall emissions reprogram. The truck now has very slow acceleration when cold. You have to floor the throttle to get it to move when cold. Very dangerous when merging into traffic or leaving a stop. The fuel economy has dropped to 20-21 mpg from 25 and higher. It is a much different and not enjoyed truck anymore. Talked with dealer. They are very aware of the issue as almost everyone has the same problems. Nothing they can do but say "hopefully a different re flash or tune will be sent after the complaints" wishing now it was just a simple buy back offer.

Recent ECM update by fca has detuned my truck. Loss of mpg, turbo lag, causing fires.

After V08/V11 recall was performed I now experience loss of acceleration till warm up. Like a dead pedal. Also a loss of a confirmed 5-6mpg. It was stated in the recall we would not loose mileage. If we did it would be very minimal. 5mpg is not minimal. My truck will barely stay in 8th gear now. Just bouncing between 7th and 8th. Now everyone is worried about all the fires due to egr valves sticking open and causing the plastic intake manifolds to catch fire. My wife is very nervous to take it on trips or even park it in the garage. We had new smoke detectors added in garage incase truck does catch on fire. Please look into these issues. There are more than you think. Pedal issue, loss of fuel mileage, engine compartment fires. Thanks

Fiat Chrysler (fca) recently settled a class action lawsuit affecting my Ram ecodiesel truck. After that settlement, I was required to get a software flash called the "approved emissions modificatoin" (aem). After receiving that software "fix", my truck drives notably different and is now very dangerous due to the huge drop in power and increase in turbo lag. Especially when the engine is cold or not completely up to operating temperature, I experience almost no throttle response when pulling out onto a highway by my house. There is a huge amount of turbo lag, to the tune of several seconds, which makes pulling out into traffic a very dangerous event. This was never an issue prior to the required aem update, so I'm filing a complaint to outline this drastic decrease in performance which is downright dangerous for thousands if not millions of Ram and Jeep customers.

When I got my truck it ran good pulled great and got fantastic fuel mileage. I had the recall done the VO8 ref lash, since that was done my mileage has dropped 5/8 miles per gallon their is a bad throttle lag and no power coming off a stop my egr has broken and replaced under warranty and one I can hardly get 21 miles per gallon by it self on the highway and the transmission will not stay in 8th gear like it did when I first bought it. I have been all over the eastern U S with no problem pulling enclosed trailers ands 35 hp 4/4 tractor getting 19 to 22 miles per gallon at 7/5 to 80 miles per hour and staying in 8 the gear. Now no power and you have to stay in it to make it pull and trans. Shifts from 6/7 all the time and fuel mileage is terable as low as 16.6 I will no longer use that truck to go on desaster relief any more because it is scared to drive. It use to be a fun truck to drive but not now I am 70 years old and a pree mechanic and this truck stinks now I am ashamed to talk it up anymore like I did when it was new I guess when it fails I will put it in the front yard with a lemon sign on it and leave it I am one dissatified customer and I have 4 Dodge but will not own another one unless these are fixed like they were when they were new.

Power is off, throttle lag is bad turbo will not spool up until high RPM, transmission won't stay in 8 gear with the slightest incline and shifts back and forth from 6/7/8 when pulling small loads and with big loads it use to stay in 8th gear almost all the time fuel mileage is down by 6/8 miles to the gallon all this has happened after the VO8 recall, had to have a egr cooler and pipe put on because it went into limp mode, truck is scary to drive now you never know when is will excellerate when you push the gas some times it will take up to 5 seconds before it start pulling and I have a I cling going out of my drive and it almost stalls when going out in the morning and after it warms up it will throw drivel when it finally strts pulling. This winter will be bad when it gets cold because it is bad sluggish in the morning truck is scared to drive now compared to before the VO8 flash.fca could come up with something to cure this problem and Mississippi has nothing to do with californiapolution standard. My truck was running fine and getting fantastic fuel mileage before this and now it hard to get 20/21 out of it on the road where I was getting 28/30 you could stand behind my truck befor flash and not smell nothing but now it will burn your nose. Test were run befor VO8 crackle and it met pollution standards how did fca get sued for passing the standards I guess cal just doesn't like diesels, don't think I will ever go to California or buy another fca vehicle I guess I will go back to Toyota when this truck quits which will be very soon with all the cells coming on now, we need help on a use to be very good truck. It was fun to drive when I first got it but not any more. I use this truck to pull a tractor all over the U/S for desaster relief work but I will not take it any more because of how it runs now, really scary to pull stuff now compared to before flash

Since having the approved emissions modification done on my Ram ecodiesel the truck will not accelerate properly until the engine seems to reach full operating temperature. When I attempt to pull onto another highway the engine bogs down and acts like it is going to stall. I believe this to be an unsafe driving condition. With colder weather approaching I am concerned this issue may worsen.

After an emissions recall update was performed on my 2015 Ram eco diesel I now experience lower mpg and poor engine performance along with a noticeable change in transmission shifting.. at times when pulling onto a highway from a stopped position the vehicle hesitates for a bit then seems to accelerate okay. This has become a safety concern do to the fact it isn't consistent. I have to be extremely careful when accelerating because I was close to causing an accident a few times already. Before the emissions update I did not experience any problems.

Did the flash upgrade to fix the recall V08 and ever since then it has no acceleration when coming off a stop. It has a lag of a second or two and is very scary when trying to pull out in traffic. It has such a lag that pulling out that that your not sure that you wont get in a accident.

Involving the eco diesel emissions update performed on my 2015 Ram 1500 at the dealership by fca on 06/11/19 said it would not change the driveablity of the vehicle but it has, in the acceleration that is delayed or sometimes just not there at all, this is inconsistent and intermittent when pulling out onto a roadway I must take the possibility in mind that the vehicle might not get going into the flow of traffic, I find this to be a safety hazard for every day drivers. Thank you, please advise

I recently had the approved emissions modification performed on my 2015 Ram 1500 ecodiesel. Since the modification, the truck has a terrible lag when I take off, sometimes up to 5 seconds. This happens when I put my foot on accelerator and try to go. This lag is going to get me hit and possibly killed. Online forums of fellow Ram ecodiesel owners state the same problem. Ram needs to get this fixed and push out an update that will fix the problem or I'm going to get injured or killed in this truck. It is no longer safe to drive because of this recall modification.

After the V08 recall the drivability of vehicle is dangerous. The fuel consumption and the lag of the engine is also a huge concern but it handles totally different. While it still seems decently reliable, for now, everyday unsureness of trying to anticipate how the vehicle will handle during driving is the primary factor.

After having recall, V08 done on my 2015 Ram 1500 ecodiesel truck. I have an extreme lag when taking off. It is so bad it could be dangerous when merging into traffic from a complete stop. It is a dead pedal with no acceleration when you push down on pedal. This occurs when ever I accelerate from a stop. I did not have this issue before the V08 update. I have heard this is a very wide problem among Ram 1500's that have had V08 completed. Is there a fix or update to correct this issue?

After receiving my truck back from a Ram dealership who preformed the required aem emissions recall, it has not run the same. The is a noticeable mpg drop both in the city and on the highway. There is also a significant delay in the response of the truck when trying to accelerate. This is noticeable when lightly accelerating while in traffic or when you have to aggressively accelerate to either avoid another vehicle or when getting up to speed of moving traffic.

V08 recall. Acceleration from any speed, including standing start is dangerously delayed, pulling into and across traffic is unpredictable. There is no throttle response until around 70% throttle, then acceleration is unpredictable and late. Fuel consumption is beyond passable for such a potentially efficient and powerful engine. The purpose of the vehicle is light towing. The power train has been tuned to the point that it's useless, the vgt fights at above 70% capacity to maintain torque and power to the wheels. Fuel injection timing ranges from -17 to +5 degrees, only to maintain emissions efficiency, the new ECU programming completely ignores efficient engine management- focusing on emissions control. System and engine components are not designed for the crazy egt temps that come with the late fuel injection. Engine fires- intake manifold in particular- are becoming very common. Will it take a few fatalities before something is done. All to prove some epa point. I could be getting 30 plus mpg, without the egr system, still target specific exhaust gas emissions reductions and get some reliability without fearing my vehicle will burst into flames or get T-boned trying to cross traffic.

The engine blew up under warranty but was voided by aftermarket parts. The parts had nothing to do with the failure.fca knows there is a serious problem and found the easy wayout costing me thousands...
